I just doesn't work for me

[donkeyrobsbank]

Hello everyone,
I have tried several different doses during the last few days (A-Bomb, LSD, HandOfGod, Nitrous) and none of them had any effect for me at all (only somewhere in the middle of the HOG-file I suddenly started to sweat heavily).
Is there any hope it will work some day? I have heard that with some people i-doser simply doesn't work.
And I acted exactly the way one should reasonably do, my room was all dark, I closed my eyes and relaxed, I tried to think of nothing at all (which I managed pretty well), I tried to just concentrate on the sound - nothing happened. It felt like, well, just lying on my bed listening to some strange sounds, nothing special.
Also, I tried it in the evening and also in the morning.
Maybe it's because of my headphones, Sony MDR-XD100, they cost me like 30 Euros. But I have read that some people have even crappier headphones and it still works perfectly.
Should I just try other doses? Did I do something wrong? Are there any doses where the probability that they work is higher than the ones I tried? Even if it's just a question of whether or not you believe that it works, I DO believe that.

a lot of people say that vico is an easy dose to get to work - just not in my experience. Astral Projection's quite good even if you don't fully project.

Alcohol is the best starter

Thanks for the advice, I'm gonna try both tomorrow and I'll post my experiences here (though I have heard of someone who listened to the alcohol-file and after 5 minutes he had to puke).
More ideas are welcome.
